如何重写cxf MessageSenderEndingInterceptor并控制handleMessage方法

Question

我使用jaxws:client标记和spring来消费webservices。在上面的过程中，我想在调用webservice之前和之后使用cxf拦截器。

iam能够与cxf拦截器一起使用webservice返回正确的皂故障和成功响应，但在Http状态代码：404的情况下以及服务关闭时不会调用inFaultInterceptor...连接异常...

分析错误后...我发现异常是从https://cxf.apache.org/javadoc/latest/org/apache/cxf/interceptor/MessageSenderInterceptor.MessageSenderEndingInterceptor.html抛出的

    private Conduit getConduit(Message message) {
        Exchange exchange = message.getExchange();
        Conduit conduit = exchange.getConduit(message);
        if (conduit == null
            && (exchange.getOutMessage() != null
                || exchange.getOutFaultMessage() != null)) {
            conduit = OutgoingChainInterceptor.getBackChannelConduit(message);
        }
        return conduit;
    }

 }

我的问题是：如何在我们的项目中重写这个类，以便定制内部类的handleMessage？在抛出cxf fault with Cannot send消息之前，我必须在故障侦听器中获得控制权。。。

您可以使用添加到CXF总线的FaultListener。监听器还将捕获http异常（示例为404），允许您在将其引发到调用方法之前执行代码。

举个例子

public class CxfFaultListenerImpl implements FaultListener{
    public boolean faultOccurred(final Exception exception,final String description,final Message message) {

        //return false to avoid standard CXF logging of exception
        return false;
    }
}

Spring CXF配置

<cxf:bus>
 <cxf:properties>
    <entry key="org.apache.cxf.logging.FaultListener">
        <bean id="cxfFaultListener" class="CxfFaultListenerImpl" />
    </entry>
 </cxf:properties>
</cxf:bus>
